• Rigorous Quality Testing Processes:
At IT-MAG, quality is not an afterthought—it’s embedded in every step of the manufacturing process. The company maintains a fully equipped laboratory (Lab Mark: Lab, Ref: 03-280) where each batch undergoes comprehensive testing before shipment. Key quality control procedures include magnetic force testing using Hall probes and fluxmeters to verify Br, Hc, and BHmax; high-frequency infrared carbon and sulfur analysis to ensure precise chemical composition; X-ray fluorescence (XRF) and Inductively Coupled Plasma (ICP) spectrometry for elemental accuracy; salt spray tests (SST) and constant temperature/humidity cycling to assess corrosion resistance; and high/low temperature impact tests to simulate real-world stress. Every magnet undergoes germ inspection post-pressing, sintering, and final machining to detect micro-defects. For example, during the GBD process, temperature profiles are monitored within ±5℃ precision to ensure uniform diffusion of Dy/Tb into grain boundaries. All test data is documented and traceable, ensuring compliance with customer specifications. IT-MAG also conducts accelerated aging tests at 120℃ and 150℃, demonstrating that GBD-treated magnets retain up to 90% of their coercivity even after prolonged exposure—far exceeding industry standards. These rigorous protocols guarantee that every magnet shipped meets the highest benchmarks for performance, safety, and longevity, reinforcing IT-MAG’s reputation as a dependable partner for critical applications.

• Advanced Grain Boundary Diffusion Technology:
One of IT-MAG’s most significant technological breakthroughs is its mastery of Grain Boundary Diffusion (GBD) technology—a revolutionary method that enhances magnet performance without compromising magnetic strength. Traditional approaches to increasing coercivity require adding heavy rare earth elements (HREs) like dysprosium (Dy) or terbium (Tb) throughout the entire magnet body, which increases cost and reduces remanence. IT-MAG’s GBD process overcomes this limitation by selectively depositing Dy/Tb onto the surface of sintered NdFeB blanks, then diffusing them into the grain boundaries under vacuum at temperatures between 700–1000℃. This targeted approach allows for a dramatic increase in intrinsic coercive force (Hci)—from 12 KOe to over 40 KOe—while maintaining high remanence. The result? High-grade magnets like N55H, N52UH, and N50KH that perform reliably at temperatures above 150℃, making them ideal for electric vehicle motors, wind turbines, and industrial drives. Performance data shows that after GBD treatment, magnets retain 1.2 kg of magnetic force at 120℃ (vs. 9 kg before), and 1.5 kg at 150℃ (vs. 8 kg before)—a clear indicator of enhanced thermal stability. IT-MAG’s GBD process also reduces overall HRE usage by up to 40%, lowering costs and environmental impact. This innovation has enabled IT-MAG to supply magnets for high-end automotive sensors used in Ferrari and FIAT vehicles, where precision and durability are non-negotiable. By combining cutting-edge science with industrial scalability, IT-MAG continues to push the boundaries of what neodymium magnets can achieve.
